Implement the oil-supplementing system of the present invention for grinding machine dynamic and hydrostatic bearing,
Before grinding machine startup, controller 2 detects the oil pressure of accumulator 3 by pressure sensor 7, when the oil pressure of accumulator 3
During less than setting value, the dead electricity of normally closed solenoid valve 4, normally open solenoid valve 6 obtain electric, high-pressure pump 12 and started, the lubricating oil in fuel reserve tank 13
Check valve 10 and valve A15 are passed through in the presence of high-pressure pump 12, is reached in accumulator 3, starts to carry out topping up to accumulator 3,
When pressure reaches requirement, pressure sensor 7 sends signal, and controller 2 sends instruction so that high-pressure pump 12 stops to accumulator 3
Topping up；
When grinding machine prepares to start, controller 2 sends instruction and starts low-lift pump 11 and high-pressure pump 12 successively, now normally closed electricity
Magnet valve 4, normally open solenoid valve 6 it is electric, the lubricating oil in fuel reserve tank 13 is opened in the presence of high-pressure pump 12 through normally closed solenoid valve 4
Begin to the fuel feeding of dynamic and hydrostatic bearing 1, after the lubricating oil in dynamic and hydrostatic bearing 1 reaches certain floatation volume, grinding machine can start, with
This stores enough energy, in packing state simultaneously in accumulator 3.
According to the operation principle of grinding machine dynamic and hydrostatic bearing, when grinding machine reaches rated speed, high-pressure pump 12 is stopped, only
Low-lift pump 11 works, and now accumulator 3 is just constantly in packing state after being full of oil, the oil supply gallery such as caused by oil leakage
Interior pressure declines and is less than setting value, and now pressure sensor 7 is signaled to controller 2, can be again started up high-pressure pump 12, this
When normally closed solenoid valve 4 dead electricity, normally open solenoid valve 6 it is electric, accumulator 3 can be carried out again oil-filled, pressure passes when reaching setting value
Sensor 7 sends signal, is automatically stopped by the high-pressure pump 12 of controller 2, if but because pressure holding effect is bad or other reasonses, make
Oil is frequently rushed repeatedly to accumulator 3 to the signal of high-pressure pump 12 into pressure sensor 7, answers maintenance down；
Cause oil supply system to paralyse when there is fortuitous event, controller 2 detects and sends signal, now normally closed solenoid valve 4,
6 equal dead electricity of normally open solenoid valve, lubricating oil in accumulator 3 through flow speed control valve 5 and normally open solenoid valve 6 to the repairing of dynamic and hydrostatic bearing 1,
Ensure dynamic and hydrostatic bearing 1 from damage；
When the oil pressure of lubricating oil in accumulator 3 is excessive, during higher than setting value, overflow valve 17 starts, by unnecessary lubricating oil
Fuel reserve tank 13 is flowed back to through drainback passage 14, when oil supply gallery needs maintenance, Open valve B16, the lubricating oil in accumulator 3 is worn
Valve B16 is crossed, fuel reserve tank 13 is flowed back to through drainback passage 14, by the lubrication evacuation in accumulator 3, staff when usually using
Pressure gauge 9 can also be often checked, obtains the pressure data in the oil supply gallery of accumulator 3 in time.
Part not in the detailed description of the invention is prior art.
